“The Rare Earth Association is still in the process of preparation. The president of the association will be held by the CEOs of the leading enterprises in the industry. At present, Zhou Bingli , chairman of Baotou Steel Rare Earth ( 59.87 , 1.32 , 2.25% ) , is likely to serve as the first president of the association. On January 26, a person familiar with the preparations for the China Rare Earth Association revealed to the reporter of China Times. The source said that the materials for the construction of the China Rare Earth Industry Association have been approved by the Ministry of Industry and Information Technology, and also approved by the civil affairs department. The association is expected to be officially established in May this year. There are more than 90 member companies, which basically cover the development of major rare earths in the country. Smelting enterprises. After the official establishment of China Rare Earth Industry Association, it will lead a new round of industry restructuring and resource integration with the Ministry of Industry and Information Technology. It is also known that the State Development and Reform Commission's State Reserve Bureau is drafting new guidelines for the implementation of the guidelines for the implementation of the reserve, and plans to raise the voluntary storage of Baotou Steel's rare earth enterprises to the level of national reserves. Baotou Steel Rare Earth or Leading Previously, this newspaper reported that Wang Caifeng, the head of the preparatory group of the association and the former deputy director of the Raw Materials Department of the Ministry of Industry and Information Technology, will be the first secretary-general and vice president. A few days ago, Wang Caifeng confirmed in an interview with the media that "the preparatory work for the preparation of the association has been completed, including the research and formulation of the association's articles of association, the convening of members, and has now been reported to the Ministry of Industry and Information Technology, waiting for the industry management opinions." However, according to the above-mentioned insiders The pace of preparations is much faster. "Now it can be established at any time." In order to prepare more fully, it is most likely to be listed in May. Previously, Wang Caifeng had denied the possibility of listing in March. "Being able to become the first director unit, Baotou Steel Rare Earth should be expected, and Chairman Zhou Bingli is likely to be the first president of the Rare Earth Association." The source said. Baotou Steel Rare Earth is a veritable “boss†in the rare earth industry. It is backed by Baiyun Obo Iron Mine, which is the largest rare earth mine in China, accounting for 87.1% of the proven reserves in China. Since 2008, Baotou Steel Rare Earth Joint Subsidiary and other enterprises have established Inner Mongolia Baotou Steel Rare Earth International Trading Co., Ltd., which has acquired and directed the sale of rare earth oxides and rare earth metals with Baiyun Obo as raw materials, and has compiled more The home rare earth processing enterprise has further mastered the right to speak of rare earth prices. Zhou Bingli, who was elected as the chairman of the board last July, also serves as the chairman of Baotou Steel Group. Under his auspices, in 2010, Baotou Steel further strengthened the protection of rare earth resources on the basis of the original, and carried out special rectification of minerals development order such as rare earth, and achieved remarkable results. "In the future, Baotou Steel will rely on resources reasonably, actively explore the extension of the rare earth industry chain, achieve high-quality, high-efficiency use of rare earth resources, and promote new breakthroughs in China's rare earth industry." Zhou Bingli is also promoting the preparations for the association. It is reported that the chairman of the China Rare Earth Association will be held by the leading companies in the industry in turn, and Minmetals Group, China Nonferrous Metals, Guangzhao Nonferrous Metals and other industry leaders will also be selected as governing units. It is reported that Minmetals will be the chairman unit of the association, because although Baotou Steel has the largest production of rare earths, due to the need for more coordination in the export of rare earths, and Minmetals has the largest rare earth quota, rare earth enterprises will choose Minmetals. As the leader. However, the above-mentioned insiders denied this: "The main function of the association is to conduct external negotiations and internal integration, but it will focus more on the latter. Wang Caifeng’s statement is similar. “As a bridge between the government and enterprises, the association should play the role of bridges and ties, and consider how to follow the plan and do a good job of the government’s assistants. "In the next step, we must consider how to regulate the order of production and management in the industry and play a role in strengthening self-discipline in the industry." According to the proposed charter, China Rare Earth Association will provide production guidance, market research, industry management, intermediary services, trade friction warning, etc. for enterprises to play a role as a bridge between enterprises and the government and domestic and foreign markets. The form of the organization exerts greater influence on the key issues of the rare earth industry, such as export prices and export quotas. The national strategy for purchasing and upgrading is reported. After the establishment of the rare earth industry association, it will lead a new round of industry restructuring and resources together with the Ministry of Industry and Information Technology. Integrate and establish a rare earth reserve system. In fact, the pilot project of China's rare earth strategic resource reserve system has been launched. In February last year, Baotou Steel Rare Earth officially announced the implementation of the strategic reserve plan for Baotou rare earth raw materials and the construction of 10 rare earth oxide storage facilities (mainly Light rare earth concentrate resources, total reserves exceed 200,000 tons.) In December of the same year, Baozhong Rare Earth General Manager Zhang Zhong also said in an interview with the media that the reserve has been carried out for one year, and the professional reserve has been built several times. Work is being carried out normally according to the reserve plan approved by Inner Mongolia Autonomous Region. However, it has not risen to the level of national reserves for the time being. But things are changing. According to the above-mentioned insiders, the Ministry of Land and Resources has discussed the development plan for rare earths in Inner Mongolia, which has confirmed the obvious effect of rectification of rare earths in Inner Mongolia, and mentioned that “all-round promotion of rare earths Strategic resource reserve, as soon as possible to establish a national light rare earth development linkage mechanism. Previously, the Ministry of Land and Resources had publicly pointed out that mineral resources such as rare earth should ensure the completion of integration tasks by the end of 2010. A rare earth industry expert from the China Nonferrous Metals Industry Association said that "Integration is the condition for establishing a storage system. As the integration of rare earths achieves obvious results, the goal of establishing a storage system is getting closer. "At present, the State Development and Reform Commission's State Reserve Bureau is drafting new guidelines for the implementation of the guidelines for the implementation of the reserve, and plans to raise the voluntary storage of Baotou Steel's rare earth enterprises to the level of national reserves. The above-mentioned insiders revealed to the newspaper that Niu Jingxue, deputy secretary-general of the China Rare Earth Society, also said that the policy aimed at promoting industry consolidation and storage will also surface. The "Rare Earth Industry Access Standard" is determined this year. According to the introduction, the Notice of the Ministry of Industry and Information Technology on the Open Collection of Opinions on the Access Conditions for the Rare Earth Industry has two purposes: one is to lead resources or channel integration by leading enterprises, and the other is to supplement the government. The integration of mining total control, export quotas, resource storage and other measures to promote integration. The strategic reserve of rare earths is mainly based on avoiding excessive exploitation of resources, balancing the intergenerational distribution of resources, and considering the price control of some strategic resources. Niu Jingkao believes that the introduction of this standard has made substantial progress on the strategic reserve work of the rare earth industry, and will form a favorable for the rare earth industry.
At present, in the process of isolation and preparation of various stem cells from various tissue sources, Centrifuge Tubes with a volume of 15ml and 50ml are used.
It is one of the low-value consumables with high usage rate. It is generally installed on a dry foam rack with the package or in bulk. When used, it is taken out by the operator and placed on the plastic centrifuge tube rack in the ultra-clean workbench. The common centrifuge tube rack can only make the centrifuge tube stand upright. When transferring liquid or needing centrifugation, the operator should hold the centrifuge tube in the left and the night gun or aspirator in the right. If it is necessary to transfer a large amount of liquid reagents or perform gradient centrifugation operations, such as density gradient centrifugation to separate mononuclear cells, the operator needs to hold the centrifuge tube with the right hand for a long time and tilt the centrifuge tube, which often causes the operator's wrist joint pain. At the same time, it will also affect the liquid superposition effect, which will easily lead to the mixing of liquids of different densities, resulting in the failure of the experiment.
